嗨，我需要一些帮助。我有一个使用Ionic 1完成的实时流和按需播放APP，并且播放器是我使用Swift Code制作的CordovaPlugin。我正在将该应用程序迁移到React Native，并且我桥接了该插件。除直播外，其他一切正常。两种应用程序中都使用相同的代码，但是React Native程序向我抛出“操作无法完成”错误。我认为这可能是一种配置问题，但是我的Swift知识有限
谢谢！
这是视频播放器的代码。我正在使用苹果公司的FairPlay实现。重复一遍，此代码作为Cordova插件在我的Ionic应用程序中运行。但是，在React Native中，只有VOD在起作用。没有直播。
